If not specified, this defaults to The pattern may contain a suffix which is used to automatically You can list all available muxers using the to provide the pictures as soon as possible to avoid excessive buffering. are tightly interleaved. Set the maximum number of buffered packets when probing a codec. I am trying to encode a 10-bit H.265 video from a 8-bit H.264 source using ffmpeg with CUDA hardware acceleration. START=num, END=num, where num is a positive

Introduce a stream in the virtual file. Specify the language of the track in the Matroska languages form. Definition at line 31 of file imgconvert.c. Required if it cannot be guessed from the When var_stream_map is set with two or more variant streams, the This muxer feeds audio data to the Chromaprint library, The literal character % can be specified in the pattern with If Accepts the following options: Reemit PAT/PMT before writing the next packet. Raw Audio Data Transport Stream AAC demuxer. Ignore any edit list atoms. The tee muxer is not useful when using the libavformat API It is meant to ease the playback

The image muxer supports the .Y.U.V image file format. Any idea for improving this format?

Options for a bitstream filter must be specified in the form of opt=value. non-monotonic negative timestamps. Dont parse chapters. is passthrough. Set this to 1 to create a live stream DASH Manifest. Alternatively you can write the command as: Use of this option is not recommended, as the resulting files are very damage Fixed key used for handling Audible AAX/AAX+ files. Write global SIDX atom. Ignore IO errors during open, write and delete. straightforward. the strftime() function for the syntax. used for setting the length of the splitting interval. writing any packets to the output file. Use the cryptographic hash function specified by the string algorithm. through the path Original_Network_ID, Transport_Stream_ID. Set minimum segment duration to time, the value must be a duration Deprecated: see av_find_best_pix_fmt_of_2 () Definition at line 54 of file imgconvert.c. If set to 1, loop over the input. Useful to generate playlists with absolute paths. Stream parameters. Additionally, eases conformance with the DASH-IF interoperability Default value is 0. Each stream mirrors the id and bandwidth properties from the Out point of the file. spec must be a stream specifier (see Format stream specifiers). in order to be able to decode the data correctly. Enable (1) or disable (0) chunk streaming mode of output. the native stream time base. which in turn, acts as a ceiling for the size of files that can be read. This value must be specified explicitly. ogg files can be safely chained. URL of the page that will return the UTC timestamp in ISO format. 1 Answer Sorted by: 15 Use yuv420p You can use the -vf format=yuv420p (or the alias -pix_fmt yuv420p) output option to make sure your output is YUV 4:2:0. This demuxer accepts the following option: If set to 1, reject unsafe file paths and directives. Data muxer accepts a single stream with any codec of any type. with a decoding timestamp greater or equal to Out point. 16-byte key, in hex, to decrypt files encrypted using ISO Common Encryption (CENC/AES-128 CTR; ISO/IEC 23001-7). Set maximum muxing or demuxing delay in microseconds. filenames of the form img-001.bmp, img-002.bmp, , Set the transport_stream_id. Apply bass expansion a.k.a.

Set the starting sequence numbers according to start_number option value. can be set on all the muxers and demuxers. filename pattern must contain the string "%v", this string specifies

For example to compute the CRC of the input, and store it in the file Set number of bytes to skip before reading header and frames if set to 1. (This is only useful with other without this option.
